PATENT JOHN O. VANDS, OF ST. LOUIS, MISSOURI.

CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 496,332, dated April25, 1893.

Application filed August Z7, 1892. Serial No. 444,294. (N o model.)

To all whom, it may concern,.-

Be it known that I, JOHN C. WANDs, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inOar-Roofs, of which the following is a full, clear, and exactdescription, referencebeing had to the accompanying drawings, formingpart of this specification.

My invention relates to a certain improvement in that class of carroofs, wherein sheets of metal, extending from one side of the roof tothe other, have been employed; and myinvention consists in features ofnovelty7 hereinafter fully described and pointed out in the claims.

Figure I is a top or plan view, illustrative of my invention. Fig; II isa transverse section, taken on line II-II, Fig. I. Fig. III is anenlarged, detail, vertical section, taken on line III-IIL Fig. I. Fig.IV is a perspective view of the inner end of one of the loose sheets.Fig. V is a perspective View of one of the caps or joints. Fig. VI is anenlarged, vertical section, taken on line VI-VI, Fig.I; and Fig. VII isa similar View, taken on line VII-VII, Fig. I.

Referring to the drawings, l represents the body of the car, 3 thecarlings, 4 the longitudinal plates placed at the upper corners of thecar-body; 7 the frieze-board, 8 the longitudinal strips or purlins,which support the sheets of metal; 9 the outer covering of the roof,supported on longitudinal strips or purlins l0; 11 the running-board; 12metal sheets covering the purlins 8, and which are fastened or securedto the body of the car at their outer ends, as shown at 13, Figs. II andVI. It takes a number of the sheets 12 to cover the roof, and they arejoined at their edges by moldings or ribs let, (see Figs. I and VIL)which are grooved at 15 to receive the edges of the sheets, as shownclearly in Fig. VII; the moldings or ribs may be covered by a metal cap16. The moldings are bolted to the purlins 8, as shown in Fig. VII.

Heretofore it has been customary to make the sheets 12 extend from sideto side of the roof. This practice has been found objectionable, as itaffords no opportunity for the working of the roof, in the movement ofaheavily loaded car over rough tracks, and my inveng tion is intended toovercome this objection by providing for a movement of the sheets andavoiding their buckling or tearing. I accomplish this by extending eachsheet 12 from the outer edge of the roof up nearly to the ridge of theroof, where each sheet is provided with a short return bend 19, (seeFigs. III and IV.) The adjacent edges of two sheets are then joined by aconnecting cap or member 20, (see Figs. III and V,) which is providedwith return bends 2l, which lock and tit into the bends 19 of the sheets12. It will thusbe seen that the sheets on opposite sides of the roofare connected together in such a manner that they can move freely.

The connecting caps or members 20 have end flanges 22, corresponding tothe flanges 12a on the sheets l2, which fit in the grooves l5 of theribs 14.

I claim as my invention- 1. In combination with acarroof,the transversesheets fixed to the vedges of the carroof, having their edgestransversely of the car connected by a suitable molding as shown,extending up to near the ridge of the roof with unobstructed spacebetween them, whereby the sheets may move transversely of the car andcompensate for twisting of the same, and the cap plate formedsubstantially as described with the transverse flanges conforming to thejoints of the sheets running transversely of the car, for the purposeset forth.

2. In combination witha car roof, the transverse sheets Xed to the edgesof the car root', having their edges transversely of the car connectedby a suitable molding as shown, eX- tending up to near the ridge of theroof, and formed with return bends which run longitudinally of the carwith unobstructed space between them, whereby the sheets may movetransversely of the car and compensate for twisting of the same, and thecap-plate formed substantially as described with the longitudinal bendsengaging the return bends of the transverse sheets, and also with thetrans? verse flanges conforming to the joints of the sheets runningtrausverselv of the car, for the purpose set forth.

3. In combination with acar roof, the trans- IOO verse sheets fixed attheir outer ends to the edges of said roof extendn g up to the ridge andformed with return bends running longitudinally of Jthe ear withunobstructed space between opposite sheets, the transverse moidn gstrips having grooves in which the edges of the sheets fit, and thecap-plate havingbends en gaging the return bends but not opposing themovement of the sheets, and having anges conforming to and entering thegrooves 1c in the molding strips, all substantially as set forth.
